Having the method of dumping out there could allow people with different (older?) firmware versions to dump their firmware which could lead to the discovery of some security holes that $ony patched and that were never found.

Oh yeh i fully understand that as being another benefit to having a tutorial on how it was done

When replying to the post I quoted though, they asked if any of the dev's understood how it could be done and then possibly recreate the process, where I wanted to point out that for dev's recreating the process would be unnecessary at this point unless they wish to try and experiment with other ways of finding an expolit but using this method of dumping the GameOS.

If people out there wish to recreate the process though, that is one of the bonus's of DemonHades and JaicraB sharing the method used

Also if someone does this on an older FW and discovers an exploit, then there's always the possibility of finding a way to downgrade and then use the exploit from there
